Intermodal connections with other scheduled public transportation modes are available at 70 percent of all stations 

served by commuter rail trains. Commuter rail passengers 

are able to connect to other transportation modes at 8121 of 

the 1,160 stations served by commuter trains that operate 

over the tracks of the national rail network.2 The percentage of commuter rail stations with intermodal connectivity 

exceeds that of the other modes (airline, intercity rail, and 

ferries) included thus far in the Bureau of Transportation 

Statistics’ Intermodal Passenger Connectivity Database 

(IPCD). 

The commuter rail network covers 34 metropolitan areas 

across the country and provides regional rail service within 

a single or two adjacent metropolitan areas. Commuter 

trains, which may be either diesel or electrically powered, 

operate over tracks of the national rail system, frequently 

sharing the same right-of-way with freight trains or intercity 

passenger trains. They generally operate from outlying stations within a metropolitan area to the predominant city in 

that area.3

 However, a few commuter rail systems operate 

between adjacent metropolitan areas. 

transit networks, and so commuter rail stations are frequently served by local transit buses. Transit bus is, by far,

 Recently, 1,067 commuter rail stations were added to the database. In addition, 92 

intercity rail stations, already in the IPCD, are also served by commuter trains. One

the U.S. commuter rail network are metropolitan in nature. A metro area contains a

core of at least 10,000 (but less than 50,000) population.

the most frequent connection to commuter rail networks, 

serving 801 of the 812 commuter rail stations that have 

intermodal connections. These connections effectively 

extend access to the commuter rail network beyond the immediate station area to the wider area served by the transit 

bus network.4

 Some of the stations also have intercity (long 

distance) transportation service, such as intercity bus, intercity rail, interstate ferries, or airline service. 

Intermodal commuter rail stations offer residents within the 

commuter rail service area a way to use the trains to connect to region- and nation-wide destinations. Not only do 

these intermodal commuter rail stations provide the opportunity to connect between modes, but by offering multiple 

modes in a single location they help create more livable 

communities by offering multiple travel mode choices in a 

single location to the residents of the immediate surrounding areas.

 In many cases, the local transit bus system is operated by the same transit authority 

that operates the commuter rail network.

Connecting Options at Commuter Rail 

Stations

Of the 812 commuter rail stations where intermodal connections are available, 734 (90 percent) have connections 

with a single other mode. Transit bus is the connecting 

mode at 723 of those 734 stations. At 75 stations there are 

two modes connecting to commuter rail, and three stations 

are served by three modes in addition to rail.5

In addition to the 812 commuter rail stations with connections to other modes, there are also 79 stations that are 

classified as having “near connections.” In these cases, 

there are no modes other than commuter rail directly 

serving the train station, but service from another modal 

subcategory stops within one or two blocks. Due to the 

physical separation of the modes they are not classified in 

the IPCD as connecting. The IPCD only classifies service 

in the same building or services located adjacent to each 

other as an intermodal connection. However, when connections are located within a few blocks of each other, they 

are considered a “near connection.” Although not classified 

as a connection, many travelers may attempt to connect 

between the nearby modes.6

5

 The three stations served by three modes in addition to standard rail service are 

Hoboken, NJ (transit rail, transit bus and transit ferries), O’Hare Airport Transfer 

Station (transit rail, transit and intercity bus, and air service), and BWI Thurgood 

Marshall Airport (transit rail, transit bus and air service). BWI is also served by 

intercity rail, but for purposes of identifying major modes of passenger transportation, 

intercity rail and commuter rail are both considered the same mode (standard rail). 

See Box A.

6

 The BTS Technical Report, The Background, Criteria, and Usage of the Intermodal 

Passenger Connectivity Database, February 2009, discusses how connections and 

near connections are determined.

In addition to the stations with intermodal connections and 

those with nearby connections, there are 55 stations where 

other modes serve the community but not at or near the 

commuter rail station. Table 1 outlines the availability of 

connections to each of the other modes at stations in the 

commuter rail network.

There are 214 commuter rail stations in communities that 

have no other scheduled passenger transportation facility; 

clearly intermodal connections are not possible in these 

locations. When only commuter rail stations in communities with other transportation modes are considered, the 

percentage of stations with intermodal links goes up to 86 

percent from the overall 70 percent mark.

Buses and intercity rail are the most highly connected 

modes with commuter rail. Commuter rail connects with 

transit bus in nearly 86 percent of commuter rail communities where transit bus service is present in addition to 

commuter rail. Code share buses and supplemental buses, 

two special categories of bus service operated as elements 

of an intermodal transportation system, connect with commuter rail in almost 90 percent of communities they both 

serve. The code share and supplemental bus services are 

discussed in more detail below in the section on links to 

intercity transportation. 

Intercity rail shares 92 stations with commuter rail and is 

connected in 86 percent of all communities served by both 

intercity and commuter rail. Figure 1, shows the degree of 

connectivity between commuter rail and each of the other 

categories of scheduled passenger service, considering 

only communities where both modes are located.

Box A: How are Modes Defined?

The Intermodal Passenger Connectivity Database categorizes scheduled passenger transportation services by five 

major mode categories and a total of 11 subcategories. 

The major categories and their sub-categories are:

Most of the analyses presented in this report discuss 

connections to the major mode categories shown above. 

However, the report also examines connections between 

intercity and transit modes. The intercity and transit 

modes include the following sub-categories of service:

four connecting status categories. “Connections” indicates the number of commuter rail stations where the mode listed is either in the 

commuter rail station, directly outside, or within one block. “Near connections” means the connecting mode is within 1-2 blocks or is in the 

commuter rail station but operates during hours that commuter rail does not. “No connection” means the mode shown serves the same 

town/city/ municipality as commuter rail, but does not serve the commuter rail station nor comes close enough to be considered a “near 

connection.” “No service” shows the number of commuter rail stations where the other mode does not serve the same town/city/municipality as the commuter rail station.

Supplemental and Code Share buses that are in the database are not included in the totals in this table since they are not classified in 

the database as either intercity or transit.

Commuter Rail and Intercity Rail Connectivity 

Compared

Connectivity at the 1,160 commuter rail stations is much 

higher than connectivity at the intercity rail stations examined in a previously issued BTS Special Report.7

 Connections to bus, transit rail, ferry or air service are present at 

70 percent of stations served by commuter rail, but at only 

52 percent of stations served by intercity rail. The figures 

for commuter and intercity include the 92 stations that are 

served by both of these categories of rail service. Stations 

served solely by commuter rail also are more likely to have 

connectivity with other modes (68 percent) than stations 

served by intercity rail only (43 percent). However, the highest degree of connectivity is at rail stations served by both 

intercity and commuter rail. Other modes serve 96 percent 

of jointly served commuter and intercity rail stations.

Table 2 shows the connectivity for intercity, commuter, and 

the 92 stations that are jointly served by both intercity and 

commuter rail service.

Links to Intercity Transportation

Commuter rail serves 111 stations where passengers can 

make connections to intercity transportation modes. The 

most prevalent connection with intercity transportation is to 

intercity rail service operated by Amtrak, since commuter 

and intercity rail operate over the same tracks and serve 

the same stations at 92 locations. Figure 2 shows the metro 

areas where commuter rail operates, and the stations with 

commuter rail/intercity rail connections. 

Even though nonrail intercity modes do not serve rail stations as their primary terminal, transfer can also be made 

at some locations to interstate ferries, intercity buses, and 

airline service. There are 40 stations with connections to 

intercity bus, 11 with connections to air service, and 2 with

there were 528 intercity rail stations in the database; there are currently 529.

connections to interstate ferries, as well as the 92 stations 

with connections to intercity rail. Some stations have links 

to more than one intercity mode.

Ferry Connections

At two locations, both in Connecticut, commuter rail passengers can connect to intercity ferry service. At Bridgeport 

(served by Metro-North and Shoreline East commuter 

trains) ferries depart from the adjacent pier en route across 

Long Island Sound to Port Jefferson. At New London 

(served by Shoreline East), Long Island Sound ferries 

depart for Orient Point, Fisher’s Island, and Block Island. 

Commuter rail passengers can also connect with transit 

(local) ferries at seven stations—three in New York State 

(Beacon, Greenport, and Ossining); Hoboken, NJ; the two 

main stations in Chicago (Union Station and Oglivie Transportation Center); and two in Washington State (Edmonds

and Mukilteo). Figure 3 shows commuter rail connections 

with both interstate and transit ferries.

Commuter Rail at Airports

Commuter rail provides service to 8 airports, through 11 

commuter rail stations. At two of those airports, South 

Bend, IN, and Philadelphia, PA, trains operate directly to 

the airport terminal via an adjacent rail station. Philadelphia 

International Airport has four commuter rail stations allowing trains to directly serve each of the airport terminals. 

Four airports have commuter rail stations located physically away from the airport terminal, but linked to the airport 

terminal by the intra-airport transportation system. The Fort 

Lauderdale/Hollywood, FL, International Airport is served 

via the nearby Tri-Rail Station, where Tri-Rail operates its 

own shuttle to the airport terminal. Table 3 lists airport commuter rail stations. 

If a rail station is not physically in the airport terminal, a 

direct connection with air service is provided when the rail 

service is linked to the airport terminal building either by the

airport’s own intra-airport transportation system, or a shuttle 

operated by the rail service operator. However, a commuter 

rail service that is linked to an airport terminal only by a 

third party service provider (e.g., a local transit bus) is not 

considered to provide a direct connection with air service.

Table 3 and figure 4 show connections between commuter 

rail and airline service as of October 8, 2010. A new commuter rail station at the Providence, RI, airport is scheduled 

to open in fall 2010. 

Links With Intercity Buses

Other than intercity rail, intercity bus offers the most intercity connectivity for commuter rail passengers. Commuter 

rail passengers can directly connect at 40 stations to intercity buses, and at 7 locations where intercity bus is within 

1–2 blocks of the rail station. Unconstrained by a fixed right 

of way, intercity bus has the flexibility to move into intermodal facilities that are often planned around rail stations. 

Nevertheless, 62 commuter rail service communities are 

also served by intercity bus, yet the bus does not connect 

with the commuter trains. Frequently, intercity bus operators prefer to serve locations at or near interstate highway 

exits to result in the fastest possible travel time for through 

travelers aboard the buses. Figure 5 shows locations where 

commuter rail and intercity bus connect.

Code Share and Supplemental Bus Service

Code share buses and supplemental buses are special bus 

service categories operated specifically as elements of an 

intermodal transportation system. Code share buses operate as connections to another mode—predominantly as 

connections to intercity rail from communities that are not 

directly served by trains. The largest concentration of these 

services is in California. Some code share bus service is 

also operated in conjunction with commuter rail service, 

and there is limited airline code share bus service. In cities 

served by both commuter rail and code share bus, the commuter train usually serves the intercity rail station, which 

is where the code share bus usually operates. Thus, the 

degree of connectivity is high with code share bus is high, 

even though the code share bus is operated as a connection to intercity rail.

Another class of intermodal bus service is the supplemental bus. A supplemental bus operates along a rail route 

as an additional frequency to supplement the rail service. 

Just as with code share buses, the degree of connectivity 

with commuter rail for supplemental bus is high, because 

commuter rail is normally using the same rail station as the 

intercity rail for which the supplemental bus is operated.

 A future fact sheet will be issued to provide a more indepth look at code share and supplemental bus services.

Possibility of Additional Connections

While commuter rail has a higher percentage of connections at its stations than the other modes in the IPCD, there 

are 79 commuter rail stations served only by commuter 

trains even though another mode has service within a few 

blocks. At 78 of those stations, the other mode is transit or 

intercity bus. The bus modes have greater flexibility than

most other modes to adjust their routes in order to establish 

intermodal connections.9 Thus, with modifications to existing routes, an even greater percentage of commuter rail 

stations could have intermodal links. Additional intermodal 

links improve mobility for the traveling public and livability 

for the communities surrounding the station through increased transportation choices for community residents.

Updates to Earlier Data

With the addition of the commuter rail station connectivity 

data to the IPCD, a few ferry terminal and airport records 

are being updated to reflect new information available 

concerning the proximity of those facilities to commuter 

rail stations. The Bridgeport, CT, ferry terminal (Facility ID 

CT0660402 in the database) will now show a connection 

with commuter rail instead of a near connection, and the 

Mukilteo, WA, ferry terminal (WA9827501) will now show 

a near connection instead of no connection. Although the 

Centreport/Dallas-Fort Worth airport commuter rail station

 Since the rail mode must operate where tracks are located, airplanes can only land 

where airports are located, and ferries must operate where there is a body of water, 

they have less flexibility than buses to alter their routes. While buses have flexibility 

to adjust routes, in concept, various operating and economic considerations when a 

route is changed may in some cases outweigh for the bus operator the advantages 

of establishing new intermodal connections. 

is connected to the airport terminal through the airport shuttle bus system, that system requires a change of shuttle 

buses to get to the terminal. Therefore, instead of finding 

that the airport has a direct connection with commuter rail, 

that connection will be classified as a near connection in 

both the commuter rail station record (TX7615501) and the 

existing database airport record (TX7526101). 

Table 4 presents the most current data on the number and 

percentage of airline-served airports, intercity rail stations, 

ferry terminals, and commuter rail stations with intermodal 

connectivity. For the modes other than commuter rail, this 

data updates the numbers in the previous special reports 

issued for those modes. Those special reports are listed at 

the end of this report in the “About This Report” section.

Upcoming Connectivity Reports

With the addition of commuter rail station data to the IPCD, 

the database now includes 2,566 passenger transportation 

facilities (airports, intercity rail stations, ferry terminals, and 

commuter rail stations). The last modes to be added to the 

database, transit rail (heavy rail and light rail) and intercity 

bus are scheduled for addition to the database in late summer/early fall 2011.

The Intermodal Passenger Connectivity Database measures the connectivity between different modes of passenger transportation by counting the 

number of passenger transportation terminals and the availability of connections among the various scheduled public transportation modes at each 

facility.When facilities of more than one mode are co-located, the facility for each mode is counted separately for purposes of total facilities. However, 

rail stations on the national network that serve both intercity and commuter rail are included in the totals for each mode, but are counted only once in 

the totals at the bottom of the table.
